Abstract

Grasping the spatial and temporal evolution of transportation carbon emissions in the western region is of great significance for promoting the high-quality development of transportation in the west and narrowing the gap between the east and the west. In this paper, on the basis of measuring the transportation carbon emissions of 11 provinces in the western region from 2013 to 2022 using the "top-down" method, the natural discontinuity method, standard deviation ellipse method and spatial correlation network method are used to reveal the evolution law from the three dimensions of regional non-equilibrium distribution characteristics, center of gravity transfer trajectory and spatial correlation. The study shows that: (1) The growth trend of transportation carbon emissions in the west is slow, and the overall unbalanced regional distribution is characterized by "high in the middle and low in the north and south"; (2) The center of gravity of transportation carbon emissions shifts from the northwest to the southwest, and the difference between the level of transportation in the area of center of gravity and the rest of the provinces increases due to the impacts of location, policy, and development, and the centripetal convergence force is enhanced; (3) There is a significant spatial correlation in the western transportation carbon emissions. There is a significant spatial correlation effect of transportation carbon emissions in the west, in which the overall correlation effect in the policy and economic drive there is an upward trend, the local correlation effect of the phenomenon of bifurcation, Northwest and Southwest China are respectively in the "low-low" and "high-high" aggregation area. The northwestern and southwestern regions are in the "low-low" and "high-high" agglomeration zones, respectively, and have formed a certain range of agglomeration effects with neighboring provinces.

Key words：

western transportation carbon emissions; regional imbalance; center of gravity shift; spatial auto-correlation
